Analog port readings are noisy? Did i destroy my analog pins???

[system]

mayfair_69:
I connect 5v to the Aref pin ... Because my sensors need a 5v supply and I thought that we have to power the sensor through it therefore

AREF does not provide power to the sensors.

Either leave AREF unconnected or connect a 0.1 uF capacitor from AREF to GND. Until you have an understanding of the purpose of AREF and how to use it correctly do not connect anything else to it.

Ohh! I use a blutooth module to send data to a hyperterminal and this requires and Aref of 5v so I have to connect that too to transmit the sensor data while connecting the sensors to the analog ports. Is this wrong??
